To hold a plate (10) for machining to a tool plate (2), before machining it is held in place by an adhesive which is spread to give an even pressure. The adhesive is spread in a thin layer of 1-5 tenths of mm as local points or strings, or in a constant and uniform layer. To hold a plate (10) for machining to a tool plate (2), before machining it is held in place by an adhesive which is spread to give an even pressure. The adhesive is spread in a thin layer of 1-5 tenths of mm as local points or strings, or in a constant and uniform layer. The adhesive contains elastomers. It is of an anaerobic polymerization, with a medium viscosity by a rapid polymerization. The adhesive is resistant to traction and shearing. The uniform pressure is through an underpressure for an additional spreading of the adhesive. After machining, the section of the machining plate (10) which is not coated with an adhesive is retracted until all the machined sections have been cleared of adhesive in succession. The machined sections are detached from the mounting surface (40) by the insertion of a thin tool between the machined sections and the surface, or by a screw bolt through them to push them clear of the surface. Machined sections of small dimensions are released by tipping. |
